Description

The discovery of the Higgs boson in 2012 reaffirmed by the Large Hadron Collider (LHC) the Standard Model (SM), detailed measurements its couplings shows a strong deviation in the production of multiple leptons at the Electroweak (EW) scale from the Standard Model (SM) Monte Carlo predictions. The elevated production of lepton could potentially provide direct evidence for new physics Beyond the Standard Model (BSM). Here we investigate the compatibility of a simplified BSM model with the observed multi-lepton anomalies in the LHC public data. The BSM model predicts the existence of a heavy scalar H with a mass of 270 GeV that decays to a SM Higgs boson in association with a scalar singlet S of 150 GeV.
